I'm working with a system that does local BLAST searches using some preconfigured BLAST databases. From what I see, these were updated within the last year, but I cannot find any current databases available that have those same names. One specific set is a non-redundant set of human protein or nucleotide sequences. The databases are named human_nr and human_nt (with various extensions as per the BLAST db format). There are others names up_sp_human (Uniprot-Swissprot human?) and up_tbl_human (Uniprot-Tremble human?), but a cannot find any similar databases on the NCBI site or other sites.
Where else should I look for such preconfigured databases?
